We see this all the time in Europe, apparently it has made its way to America.

Via Haaretz:

The Jewish leader of a Brooklyn community center says he was beaten by pro-Palestinian demonstrators in front of his children after a Brooklyn Nets game against Israeli champions Maccabi Tel Aviv at the Barclay’s Center.

Leonard Petlakh, 42, director of the Kings Bay Y, said protestors shouting “Free Palestine” and “Your people are murderers,” accosted him as he left the game in downtown Brooklyn. One of them struck Petlakh in the face, he said.

“It’s ridiculous,” Petlakh told The Forward. “It’s not about the Middle East, it’s about sports.

Petlakh suffered a broken nose and a cut that required eight stitches after the attack, which he said was being investigated by police as an anti-Semitic hate crime.

Petlakh said he hoped, “vile anti-Semitic hooligans masquerading as anti-Zionists will be caught soon.”
